We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done in this field.
Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying factory. There it can be filtered and treated with chemicals so that it can be used again, just as it were fresh from a spring.
But even if every large city purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we’d have to do to make use of the seawater on earth is to get rid of the salt.
This process is called desalinization, and it is already in use in many parts of the world.

A.do experiments with water
B.purify the used water and reuse it
C.use fresh water once again

Other reasons they take that first drink are to be rebellious (反抗的), for curiosity or "kicks" (刺激) or to escape an unpleasant environment. And young people drink and use drugs because alcohol (酒精) and drugs are at hand.
After first experimental use, young people continue to drink or use drugs because they believe these substances can relieve boredom, increase energy, decrease anxiety, solve problems, or help them socially. They may simply like the "high" they get in the early and middle stages of substance use. After continued use, they will drink or use drugs because they become physically and psychologically (心理地) addicted (上瘾的).
Now that we have admitted that we have to solve this problem. We must decide how to deal with this challenge. Winning this will take a great effort involving local, state, and national government. It will require the effort of schools, but it cannot be done by schools alone. It will take family and com munity involvement. Already a great amount of time, energy and expert knowledge has been directed toward dealing with it but the problem continues.
Which of the following is not mentioned as the reason of drinking and using drugs in the passage？
A．the selling of alcohol and drugs
B．pressure from their parents and relatives
C．curiosity
D．their eagerness to experience what is not permissible to them
In many modem countries it has for some time been fashionable to think that, by free education for all-whether rich or poor, clever or stupid--one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees than there are jobs for them to fill. Because of their degrees, they refuse to do what they consider" low" work; and, in fact, work with the hands is thought to be dirty and shameful in such countries.
But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor, We can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we would have terrible diseases in our towns. In countries where there are no servants because everyone is ashamed to do such work, scientists have to waste much of their time doing housework.
In fact, when we say that all of us must be educated to prepare for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability and, secondly, that we can realize that all jobs are necessary to society, and it is very bad to be ashamed of one's work, or to scorn someone else's. Only such a type of education can be called valuable to society.
Education is ______.
A．a means
B．a purpose
C．fashionable
D．the first system

A major new study shows that the situation may be changing. A large and rapid drop in the world's birth rate has taken place during the past 10 years. Families generally are smaller now than they were a few years ago. It is happening in both developing and industrial nations.
Researchers said they found a number of reasons for this. More men and women are waiting longer to get married and are using birth control devices and methods to prevent or delay pregnancy. More women are going to school or working at jobs away from their homes instead of having children. And more governments, especially in developing nations, now support family planning programs to reduce population growth. China is one of the nations that has made great progress in reducing its population growth.
China has already cut its rate of population growth by about one half since 1970. China now urges each family to have no more than one child. And it hopes to reach zero population growth, the number of births equaling the number of deaths, by the year 2000.
Several nations in Europe already have fewer births than deaths. Experts said that these nations could face a serious shortage of workers in the future. And the persons who are working could face much higher taxes to help support the growing number of retired people.
In the sentence "Experts long have been concerned about such growth" of Paragraph 1, the phrase "concerned about" is similar in meaning to ______.
A．worried about
B．related to
C．engaged in
D．made a study of
A scientist who wants to predict the way in which consumers (消费者) will spend their money must study consumer behavior. He must obtain data both on the resources of consumers and on the motives that tend to encourage or discourage money spending.
If an economist were asked which of three groups borrow most — people with rising incomes, stable incomes, or decreasing incomes—he would probably answer, those with decreasing incomes. Actually in the years 1947 ~ 1950, the answer was: people with rising incomes. People with decreasing incomes were next and people with stable incomes borrowed the least. This shows us that traditional assumptions (假设) about earning and spending are not always reliable. Another traditional assumption is that if people who have money expect prices to go up they will hasten to buy. If they expect prices to go down, they will postpone buying. But research surveys have shown that this is not always true.
The expectations of price increases may not stimulate buying. One typical attitude was expressed by the wife of a mechanic in an interview at a time of rising prices. "In a few months, "she said, "we' 11 have pay more for meat and milk; we' 11 have less to spend on other things. "Her family had been planning to buy a new car but they postponed this purchase. Furthermore, the rise in prices that has already taken place may be disliked and buyer's resistance may be produced. This is shown by the following typical comment; "I just don't pay these prices; they are too high. " The investigations mentioned above were carried out in America; The condition most helpful to spending appears to be price stability. If prices have been stable and people consider that they are reasonable, they are likely to buy. Thus, it appears that the common business policy of maintaining stable prices is based on a correct understanding of consumer psychology (心理学) .
According to the passage, if one wants to predict the way spend their money, he should
A．rely on traditional assumptions about earning and spending
B．try to encourage or discourage consumers to spend money
C．carry out investigations on consumer behavior. and get data on consumers incomes and money spending motives
D．do researches in consumer psychology in a laboratory
A.has already started
B.had already started
C.had already starting
